Safety of funds at FX dealer

This topic has been rehashed to no end on ET but in light of recent events , it should be of increased concern I believe.
For ex. Oanda holds your funds with JP Morgan, so far so good for JPM but what happens if the custodian bank goes under ?
There is no FDIC here.

Anyone knows another FX dealer allowing mini lot trading with some sort of insurance on funds such as Lloyds or FDIC ?
